Nonunique
Fixed Point
Theorems on
b-Metric
Spaces Via
Simulation
Functions
Based on the
concepts of
α-orbital
admissibility
given by
Popescu in
[29] and
simulation
functions
introduced
by Khojasteh
in [25], we
introduce in
this paper
different
types of
contractive
mappings. We
also provide
some
nonunique
fixed point
results for
such
contractive
mappings in
the class of
orbital
complete
b-metric
spaces. Some
consequences
on known
results in
literature
are also
given in
support of
our obtained
results. |

On Classification of Factorable surfaces in Galilean 3-Space G3
In
this
paper,
we
study
factorable
surfaces
in
Galilean
3-space
G3.
Then
we
describe,
up
to a
congruence,
factorable
surfaces
and
the
several
results
in
this
respect
are
obtained.
In
particular,
factorable
surfaces
in
terms
of
an
isometric
immersion,
finite
type
Gauss
map
and
the
pointwise
1-type
Gauss
map
of
the
surfaces
are
considered
and
the
characterization
results
on
the
factorable
surfaces
with
respect
to
these
conditions
are
obtained.

An Existence and Convergence Results for Caputo Fractional Volterra Integro-Differential Equations
This paper demonstrates a study on some significant latest innovations in the approximated technique to find the approximate solutions of Caputo fractional Volterra integro-differential equations. To apply this, the study uses homotopy analysis method. A wider applicability of this technique is based on their reliability and reduction in the size of the computational work. This study provides analytical approximate to determine the behavior of the solution. It proves
the existence results and convergence of the solutions. In addition, it brings some examples to examine the validity and applicability of the proposed technique.

Analysis of Bivariate Survival Data Using Shared Additive Hazard Gamma Frailty Models
In this article, we propose additive hazard shared gamma frailty model
with generalized Pareto, generalized Rayleigh and xgamma distributions as baseline distribution to analyze the bivariate survival data set of McGilchrist and Aisbett [16]. Assumption of the model is that frailty acts additively to hazard rate. The Bayesian approach of Markov Chain Monte Carlo technique was employed to estimate the parameters involved in the models. We present a simulation study to
compare the true values of the parameters with the estimated values. Additive hazard shared gamma frailty model with generalized Pareto baseline distribution fits better than other propose models for kidney infection data.

Asymptotic Properties of the Conditional Hazard Function and its Maximum Estimation under Right-Censoring and Left-Truncation
Gneyou[6, 7] considered the estimation of the maximum hazard rate
under random censorship with covariate random and established strong representation and strong uniform consistency with rate of the estimate. Then he studied the asymptotic normality of his estimator. Agbokou et al.[2] generalize this work to the case of right censored and left truncated data with covariate and established strong representation and strong uniform consistency with rate of the estimate of the said estimator and of a non-parametric estimator of its maximum value. The aim of this paper is to study the asymptotic normality result of the two non-parametric estimators.

On Varietal fuzzy subgroups
Varieties of groups and fuzzy subgroups are two important concepts in
mathematics. In this paper, after presenting concepts of verbal and marginal fuzzy subgroups and discussing some of their most important characteristics of these concepts, we define variety of fuzzy subgroups and study the complete structure of this. At the end , we devote isologism of fuzzy subgroups.

On Taylor
Differential
Transform
Method for
the First
Painleve
Equation
We apply the
Taylor
Differential
Transform
Method (TDTM)
to the
initial
value
problem of
the first
Painleve
equation. We
use the
deviation to
calculate
the accuracy
of the
solutions
and the
results are
compared
with the
known
results.
Four cases
of initial
values, two
of them were
not
considered
before, are
considered
to
illustrate
the
effectiveness
of the
method. |

Sα-Connectedness
in
Topological
Spaces
In this
paper,
connectedness
of a class
of Sα-open
sets in a
topological
space X is
introduced.
The
connectedness
of this
class on X,
called Sα-
connectedness,
turns out to
be
equivalent
to
connectedness
of X when X
is locally
indiscrete
or with
finite
α-topology.
The Sα-continuous
and Sα-irresolute
mappings are
defined and
their
relationship
with other
mappings
such as
continuous
mappings and
semi-continuous
mappings are
discussed.
An
intermediate
value
theorem is
obtained.
The
hyperconnected
spaces
constitute a
subclass of
the class of
Sα-connected
spaces.

Peristaltic
Transport of
Eyring-Powell
Nanofluid in
a
Non-Uniform
Channel
In this
paper, the
effect of
MHD
peristaltic
Transport of
Eyring-Powell
Nanofluid in
a
non-uniform
channel is
studied
under long
wavelength
and low
Reynolds
number
assumptions.
Thus
peristalsis
of Eyring-Powell
nanofluid
followed
through the
conservation
principles
of mass,
momentum,
energy and
concentration
has been
modelled.
The
peristaltic
transport
equations
involves the
combined
effects of
Brownian
motion and
thermophoresis
diffussion
of
nanoparticles.
Expressions
for the
velocity,
temperature
and
concentration
are
obtained.
The effect
of various
physical
parameters
on the flow
characteristics
are shown
and
discussed
with the
help of
graphs.
